Straight answers about pricing, licensing, emergencies, and the areas we serve.
How much does an electrician charge per hour?
Per hour depends on the job and licence level, and many include a small service call fee for the first visit. Interstate Electrical Contractors keeps pricing honest and upfront so you know the cost before we start. Get a free estimate for your project by calling us.
Do you offer emergency electrician services in Glendora?
Yes. We handle urgent problems like dead outlets, sparking switches, and tripped panels that won’t reset. Same day & emergency service available to Glendora and vicinity. If you feel unsafe, turn the power off and call us right away.
Is there a difference between a certified electrician and a licensed electrician?
Yes. A licence is the legal permission of the state to perform electrical work. A certification simply demonstrates additional training in one specific skill. A licensed electrician can work solo and pull permits. A certificate alone cannot do that. Frank Chiavarini is a licensed C-10 electrical contractor in California so you get the right credentials, the real experience.
What’s the difference between an electrical contractor and an electrician?
Electricians are skilled professionals who install and repair electrical systems. An electrical contractor is the licensed business that has the insurance, assumes responsibility for the project and backs up the work. Interstate Electrical Contractors is a licensed contractor operated by a hands-on owner.
What areas do you serve besides Glendora?
We also serve Arcadia, Upland, and Diamond Bar. Not sure if you are in our territory? Just give us a quick call and we'll tell you.
How do I find a good electrician?
Look for a licensed and insured electrician with solid local reviews and upfront pricing. Ask about experience in the type of job you want, and watch out for quotes that sound too good to be true. Two simple ways to hire with confidence – check the licence number and read real customer reviews.
Are your electricians licensed and insured?

How can I save money when hiring an electrician?
Combine several small jobs on one visit to save on trip and minimum charges. Address minor issues before they become costly ones. Always hire a licensed professional. Cheap, unlicensed work can cost more to fix later. We are happy to help you decide what is most important.
